Abstract: The present disclosure envisages a system and method for self-calibration of an actuator. The system comprises a pressure spike sensing and control circuit, a travel limit setting circuit and a profile generation circuit. The pressure spike sensing and control circuit is configured to check and set an operating pressure of the actuator. The travel limit setting circuit is configured to check and set the travel limit of the actuator. The profile generation circuit is configured to generate the profiles of a set of parameters of the actuator.
